豫北地区棚室内长期栽培黄瓜、番茄、芹菜等,很难做到合理轮作,因此连作和土传病害危害较重,为了缓解这一矛盾,使作物尽可能排开播种,近2年棚室利用秋茬栽培韭菜-早春栽培黄瓜栽培模式,指导农户种植优良品种,既可倒茬、减轻病害,又可提高产量和经济效益。种植秋延后韭菜每667m~2产量约3 250kg,667m~2收入12 250元左右,省工省费、病害少;早春茬黄瓜667m~2产量约17 500kg,667m~2收入13 000元左右。现将该项高产高效栽培技术介绍如下。
Long-term cultivation of greenhouse cucumber, tomato, celery and so on in the northern part of Yubei area is difficult to achieve reasonable rotation, so continuous cropping and soil-borne diseases are more damaging. In order to alleviate this contradiction, crops are arranged as far as possible for sowing. The use of autumn cultivation of Chinese chives - early cultivation of cucumber cultivation patterns to guide farmers to grow fine varieties, both inverted crop, reduce disease, but also improve yield and economic benefits. After autumn planting, the output of leeks per 667m ~ 2 is about 3 250kg, and the income of 667m ~ 2 is about 12 250 yuan, saving labor and reducing disease; the output of early spring cucumber 667m ~ 2 is about 17 500kg, and the income of 667m ~ 2 is about 13 000 yuan . Now the high yield and efficient cultivation techniques are as follows.
